ADJUSTABLE STRAINER FOR DOWN-SPOUTS.

SPECIFICATION forming part of Letters Patent No. 725,933, dated April21, 1903.

Application filed December 5, 1902. Serial No. 134.044. .(No model.)

spouts, of which the following is a specifica-c tion.

This invention relates to strainers adapted for use on down-spouts toprevent the leaves and other foreign matter which generally accumulatesin the eaves-trough from passing into the down-spout and clogging. thesame, and has for its object to produce a simple inexpensive device ofthis character that will readily adjust itself to the interior shape orconfiguration of the down-spoutand by reason of the peculiar dispositionof the arms securely clamp the same within the spout, thereby preventingaccidental dislodgment.

Another object is to produce-a device in which the'clamping-arms aremade from a single piece of wire and secured to a central supportwithout the use of solder or other binding material.

A further object is to producea device the construction and generalarrangement of which is such that several of them may be compactlynested for shipment.

With these and other objects in view my invention consists in the novelcombination and arrangement of parts hereinafter described, and pointedout in the claims hereto appended.

In the drawings, Figure 1 is a side view of ing parts, 1 designates thestrainer, compris ing a central supporting disk or ring 2, made of sheetmetal or any suitable material and having an opening 3 in the.centerthereof. The disk 2 is preferably die-formed and is provided witha series of radiating ears 4, which may be bent to form loops 4:,adapted secures them together.

to engage the end portion 5 of spring-arm 6 and also serve to properlyspace said arms. The arms 6 are preferably formed of one continuouslength of wire, beginning at 7 and extendingoutwardly and downwardly inthe arc of a circle to the point 8, where it is bent at a'slight angle 9and'carried outwardly and downwardly in a straight plane to any desiredlength, as at 10. It is here doubled and continued upwardly and bentcorresponding to the first strand in reverse order, passing through oneof the loops 4', and'the operation continued until a sufficient numberof arms have been formed. By having the arms supported solely by thedisk 2 it renders them capable of considerable lateral expansion andcontraction, thereby permitting said arms to readily conform to theinterior shape of the spout and also permit large quantities of thestrainers being compactlynested'for shipment without increasing bulk. 1

In the manufacture of the device the disk 2 isstruckfrom a single pieceof metal with the ears 4 formed thereon and'bent upwardly and slightlyinclined toward the central opening 3. The wire is then passed undereach of said ears, the free portion'of the wire forming a series ofradiating loops 11. It is then placed in a die or former and pressed tothe desired shape or configuration, the ears 3 being firmly clamped onthe wires during the operation.

After the parts have been secured together.

and properly shaped'in theimanner stated they are submitted to theaction of the galvanizing-bath, which finishesthem and firmly I havedescribed'the arms as being formed of one continuous piece of wire; but"they may be made of several separate pieces, and various changes inform, proportions, and minor details of construction may be resorted towithout departing from the principle or sacrificing any of theadvantages of my invention.

Having thus fully described my invention, H

what I claim is p 1. A strainer comprising a supporting-piece,

and a plurality of spring-arms secured "theretoand curved outwardly anddownwardly and then inwardly and downwardly and continued into divergingend portions, such arms being unrestricted and free to expand at theirmost contracted portions sufficiently to admit the most expanded part ofthe upper portion of other like strainers, to permit nesting.

2. Astrainercomprisiugasupporting-piece, and a plurality of arms formedof one continuous piece of wire secured thereto and curved outwardly anddownwardly and then inwardly and downwardly and continued into divergingend portions, such arms being unrestricted and free to expand at theirmost contracted portions sufficiently to admit the most expanded part ofthe upper portion of other like strainers, to permit nesting.

3. A strainer comprising a central supporting-disk, ears on the disk, aplurality of arms formed of one continuous piece of wire ROBERT FRANKLINCOLEMAN.
